Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X65SCM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X65SCM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 65mm stroke, 1/4" air ports and a SUS304 stainless-steel barrel for mildly corrosive environments. For the same bore and stroke it is shorter than an ISO 6432 cylinder, saving mounting space.

About the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X65SCM
Delivering 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles heavy loads with precision. The 40 mm bore uses a 1/4" port and a 16 mm rod with an M14x1.5 male thread. A built-in piston magnet (-S) enables direct mounting of CMSG, DMSG or EMSG switches for position sensing.
A variable air cushion at both ends lets you dial in the needle valve to absorb high-speed end-of-stroke shock, protecting your machinery and reducing noise. The SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown environments. For the same bore and stroke, the MFC body is notably shorter than an ISO 6432 cylinder, saving valuable mounting length. Based on the 0.5 MPa push rating, this actuator provides a safe working load of roughly 377 N, lifting about 32 kg vertically with a 2:1 safety margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X65SCM Is Used
Heavy Package Diverting
Pushes dense cartons at high speed onto secondary lines, using the adjustable air cushion to stop the 65 mm stroke gently without jarring the conveyor frame.
Press Ejection
Ejects dense metal or plastic parts from a press bed, leveraging the 628.3 N push force and end-of-stroke deceleration to prevent part damage.
Pallet Positioning
Lifts and indexes loaded pallets up to 32 kg vertically, where the shorter JIS body length saves critical machine footprint compared to ISO 6432 alternatives.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X65SCM the Right Cylinder?
If 628.3 N at 0.5 MPa is excessive for your application, the smaller MFC32 bore provides 402.2 N of push force; as 40 mm is the largest available bore in this series, moving up requires a different cylinder family. The adjustable air cushion is essential when cycling at high speeds or moving heavy masses, as it decelerates the piston smoothly near the stroke ends.
This CM round-end rear cover model includes the -S magnet for electronic or reed sensors. Note that the air cushion only decelerates the load; it does not function as a lock or brake. Because the piston will drift if air pressure drops or the valve is centred, you must add an external rod lock or pilot-operated check valve for secure load holding.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/CM) & mount (LB/FA/SDB/TC)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check Use correct back cover (CA/U/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X65SCM FAQ
This 40 mm bore double-acting cylinder features a 1/4" port, a 16 mm piston rod and an M14x1.5 male rod thread. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, or 879.6 N push and 738.9 N pull at 0.7 MPa. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
No, the variable air cushion only decelerates the piston near the end of stroke to reduce shock; it is not a brake or lock. If air pressure drops or the valve is centred, the piston will drift. For secure load holding, you must install an external rod lock or a pilot-operated check valve.
